SICK WL11-2P2430 Photoelectric sensor
SICK WL11-2P2430 cylindrical photoelectric sensor with PNP output, part 1041385. M18-style barrel mounts through machine frame bores for easy detection.
Overview
The SICK WL11-2P2430 (part number 1041385) is a cylindrical photoelectric sensor with PNP output. Its metal barrel format mounts through a drilled hole and is secured with nuts, which makes it a practical choice for machine frames, rollers and conveyor side profiles where rectangular sensors do not fit.
How It Works
The sensor emits modulated light and evaluates the reflection from the target. When the returned light exceeds the set threshold, the output switches. The cylindrical housing places the optics at the front face, so alignment is done by pointing the barrel at the detection zone.
Key Features
- Cylindrical M18-style housing mounts through a standard bore
- PNP switching output
- Secure fixation with mounting nuts
- Visible light spot for quick orientation and alignment
- Sturdy metal barrel for demanding machine environments
- Modulated light against ambient light interference
Typical Applications
- Object detection through machine frame bores on conveyors
- Position monitoring on rotary and indexing tables
- Presence checks on packaging machine shafts and frames
- Detection in tight tubes and guide channels
- Machine tool and transfer equipment position sensing

Installation and Setup Notes
Tighten the mounting nuts evenly to keep the optical axis aligned, and use the thread lock practice common for vibrating machines. Because cylindrical sensors are often installed close to metal edges, check that the beam cone is not clipped, which would reduce range. Set the sensitivity with the real target and verify switching along the complete object travel.
Frequently Asked Questions
How is a cylindrical sensor mounted?
Through a standard bore matching the barrel diameter, secured with the supplied nuts; this suits frames, rollers and profile systems.
Can it replace a rectangular sensor?
Where a bore is available, it is often easier to install and better protected; detection behavior follows the same diffuse or retro-reflective principles depending on the variant.
Does the metal barrel affect the beam?
Only if the front face is recessed or clipped by the mounting hole; keep the optical face clear for full range.
